Self-purging pyrolysis of silk sericin composite for producing high-performance adsorbents

The role of purge gas in the preparation of bio-derived carbon remains unclear. This study explores the synergistic effects of pore structure and surface functional group changes induced by self-purging and nitrogen-purging carbonization methods on the adsorption performance of silk sericin-derived carbon. Notably, silk sericin-derived carbon produced via self-purging carbonization exhibited significantly enhanced adsorption capacities for enrofloxacin, carbon dioxide, and methylene blue—approximately 150, 14, and 3 times higher, respectively, than those of its nitrogen-purged counterpart. Experimental characterization and density functional theory simulations revealed that while surface functional groups play a crucial role in adsorption, the superior adsorption performance stems primarily from the large specific surface area and abundant microporous structure formed during self-purging carbonization. Remarkably, the maximum enrofloxacin adsorption capacity (320.78 mg/g) represents the highest value reported. These findings highlight the potential of silk sericin-derived carbon as a high-performance adsorbent for pollutant removal, enrichment, and separation. Furthermore, self-purging carbonization, which eliminates the need for external chemical activators, provides a clean, efficient route for converting silk production waste into valuable adsorbents. This work provides novel insights into the influence of pyrolysis atmospheres on adsorbent properties, advancing the design of sustainable bio-derived carbon.
